如何在VsCode中定义时间

Question

from sklearn.datasets import fetch_20newsgroups
from collections import Counter 
news = fetch_20newsgroups(subset='all')
def clean_word(word):
    return re.sub(r'[^\w\s]','',word).lower()
def word_not_in_stopwords(word):
    return word not in ENGLISH_STOP_WORDS and word and word.isalpha()


def find_top_words(news):
    cnt = Counter()
    for text in news:
        tokens_in_text = text.split()
        tokens_in_text = map(clean_word, tokens_in_text)
        tokens_in_text = filter(word_not_in_stopwords, tokens_in_text)
        cnt.update(tokens_in_text)

    return cnt.most_common(10)
%time find_top_words(news)

我在这里得到一个错误：

%time find_top_words(news)
    ^
SyntaxError: invalid syntax
